Of course Kylie and Kendall Jenner are among Nicki Minaj's millions of fans. We've known this for some time, but they proved it once again with a video uploaded on Kylie's Instagram on Thursday (May 22) with the sisters singing Nicki's new single, "Pills N Potions."

Late last year, Kylie, Kendall, Khloe and Kris joined the YMCMB rapper backstage at a Drake concert.

In 2011, there was a video of the teenage siblings singing Nicki's smash "Super Bass."

"Pills N Potions" was released on Wednesday, and will serve as the lead single for Minaj's upcoming third solo album, The Pink Print, due out later this year.
